157..............................
So this can be translated like the following:
Bike costs= 173 dollars She currently has 107. She saves 11 dollar per week to get the bike so the formula is:
173 = 107 + 11X where X is the number of weeks
Step 1: bring the 107 to the other side to get 173-107 = 11X
Step 2: divide both sides by 11 to solve for X to get this (173-107 )/11 = X
Step 3: Calculate and simplify 66 / 11 = X which is the same as X= 6
So the answer is it will take Jennifer 6 weeks to save for the bike.

Step-by-step explanation:
f(x)=x²-1, f(x-1)=(x-1)²-1
=(x-1)(x-1)-1
=(x²-x-x+1)-1
=x²-2x+1-1
=x²-2x=0
x²=2x
x=2
